FAQ
Should I follow every step exactly?
Use the guide as a shipping checklist, but cut steps that do not match your stack or MVP scope.
When should I add tests?
Add focused tests around risky logic, data transforms, auth, billing, or anything likely to regress.
What should I do if the guide feels too broad?
Break it into one acceptance criterion at a time and ask your AI editor to implement in small reviewable diffs.
